Plan9 has a lot of Wirth inspiration. Particularly the Acme text editor. The concept of text as menus is taken straight from Operon. In Acme you can use any text as an action by middle clicking and because Acme exposes it's internals via a synthetic file system you end up with a very powerful application. There are no drop down menus. Combine with the other synthetic file systems and the combination is incredibly useful. There is an email client, for instance. And my friend fgb added image viewing and now we even have a Web browser. http://en.wikipedia.org/wiki/Acme_(text_editor) http://en.wikipedia.org/wiki/Acme_(text_editor) I visited that page one day, looked at the screen shot and said "wow, that person uses Acme just like me, even using Opened" and it eventually it dawned on me that it was a screenshot of my screen I had posted elsewhere.
